Dumbbell

Abstract

A dumbbell made of heavy material has a central bar, weight knobs at opposite ends of the bar and a guard-handle spaced from the bar a distance to allow the insertion of a user's fingers between the guard-handle and the bar, the bar, weight knobs, and guard-handle being one piece. Preferably, the dumbbell is made of cast iron and coated with a resilient coating. In another embodiment, the guard handle has a center span with a long reach and a short reach, spaced axially from one another to define a belt-receiving gap.

I claim: 
     
       1. A dumbbell made of rigid material, said dumbbell having a central bar, and a rigid, inflexible guard-handle spaced from said bar a distance to allow the insertion of a user's fingers between said guard-handle and said bar, said handle having a center span with a long reach and a short reach spaced axially from one another to define a gap, said short reach defining a hook by which said dumbbell can be mounted removably on a belt of a user. 
     
     
       2. A dumbbell made of one-piece cast iron, said dumbbell having a central bar, and a guard-handle spaced from said bar a distance to allow the insertion of a user's fingers between said guard-handle and said bar, said bar and handle being one piece, said handle having a center span with a long reach and a short reach spaced axially from one another to define a gap, said short reach defining a hook by which said dumbbell can be mounted removably on a belt of a user. 
     
     
       3. A one-piece cast iron dumbbell comprising a central bar, weight knobs at opposite ends of said bar, and a guard handle spaced from said central bar a distance to allow the insertion of a user's fingers between said guard handle and said central bar, said weight knobs being uniformly polygonal, with peaks and between said peaks, valleys, said dumbbell resting on two peaks at at least one end when on a flat supporting surface, said guard handle being oriented with respect to said peaks to extend at an acute angle to the horizontal when said dumbbell is at rest on said flat surface. 
     
     
       4. The dumbbell of claim 3 wherein said peaks are rounded. 
     
     
       5. The dumbbell of claim 3 wherein the weight knobs are hexagonal in end elevation. 
     
     
       6. The dumbbell of claim 3 wherein said guard handle has a center span and, at each end of said center span, legs which join at outer ends of said legs to said bar at an inboard side of said weight knobs, meeting areas of said legs with said bar and with said center span of said handle being coved. 
     
     
       7. The dumbbell of claim 3 wherein said guard handle has a center span with a short reach and a long reach spaced axially to define between them a gap sufficiently wide to receive a belt of a user.
